摘要:
A dye solution for dyeing polyester fabric including dye, a liquid carrier, an acidic agent, and a thickening agent. The carrier is selected to enhance the permeability of the polyester fabric at a certain temperature so that the dye can penetrate within the fabric. A method of printing designs on polyester fabric including creating a dye solution with water, a dye, a carrier liquid and an acidic solution. The dye solution is applied to the fabric in a desired pattern. The fabric and dye solution are then dried in as drier so that the temperature of the carrier is raised to permit the carrier to enhance the permeability of the fabric and have the dye penetrate the fabric. The carrier is then driven out of the fabric by the dryer and no pressure is applied to the fabric during the drying process.

A non-woven fabric with melange-type visual appearance and endowed with high-durability comprising a fiber part and a matrix binder characterized by the binder matrix being a polyurethane characterized by the presence of soft segments and rigid segments, the former constituted from mixtures of polycarbonate-polyols and polyester-polyols, and the latter, from urethane groups deriving from the reaction of isocyanates with ureic polyols, and groups deriving from the reaction between the free isocyanate groups and water, and the fiber part comprises a fiber of melange appearance that is a mixture of two or more fibers with different dyeability characteristics.
摘要:
Systems and methods for coloring an article having a polyester portion and at least one portion of a second material where the polyester portion and second material are not blended together in the article. The entire article is dyed a first color, after which the first color is removed from the second material using a post reduction clear process. The entire article is then dyed a second color, which is not absorbed by the polyester portion. The system and process permit the creation of prepared for dye articles having a polyester portion of one color and a portion of a second material that is a different color.

Mixtures of different oligomer compounds of formula (1) are suitable for use as direct dyes for dyeing and printing a wide range of materials, especially cellulose fibers, to give dyeings and prints of good all-round fastness properties: ##STR1## wherein R.sub.1 is hydrogen or unsubstituted or substituted alkyl, cycloalkyl, aryl or aralkyl, R independently has the meaning of R.sub.1 or is an unsubstituted or substituted heteroaryl radical or a radical of formula ##STR2## wherein R.sub.4 is unsubstituted or substituted alkyl, cycloalkyl, aryl, aralkyl or heteroaryl, A is an unsubstituted or substituted alkylene, cycloalkylene, arylene or aralkylene radical, X is --O--, --S-- or --N(R.sub.5)--, wherein R.sub.5 is hydrogen or unsubstituted or substituted alkyl, cycloalkyl, aryl or aralkyl, or wherein the group ##STR3## is an unsubstituted or substituted heterocyclic radical, Y is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, sulfo, carboxy, carbamoyl, N-mono- or N,N-di-C.sub.1 -C.sub.4 alkylcarbamoyl, N-phenyl- or N,N-diphenylcarbamoyl, sulfamoyl, N-mono- or N,N-di-C.sub.1 -C.sub.4 alkylsulfamoyl or N-phenyl- or N,N-diphenylsulfamoyl, Z is hydroxy or unsubstituted or substituted alkyl, aryl or aralkyl, R.sub.2 and R.sub.3 are each independently of the other hydrogen, halogen, cyano, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, unsubstituted or substituted phenyl, benzyl, benzoylamino or phenoxy, sulfo, carboxy, carbamoyl, phenylcarbamoyl or C.sub.2 -C.sub.5 alkanoylamino, B is a bivalent organic linking group, m is an integer from 1 to 6 and n and p are each independently of the other 0 or 1, with the proviso that the different compounds of formula (1) of the mixture of oligomers differ solely in the value of m.
摘要:
Cellulosic fibers are converted to cellulosate by immersion in an alkali metal hydroxide and then reacted with an aqueous solution of thioarylsulfonium salts to produce modified cellulosic fibers which are substantive to acid, direct, disperse, reactive and sulfur dyes. Cellulosic/synthetic and cellulosic/wool blends can also be treated to produce a fabric blend comprising modified cellulosic components that are substantive to diverse dye classes and synthetic and wool components which are substantive to a single dye class. When using a disperse dyebath of one color the entire fabric blend is dyed one color. When adding an acid, reactive or sulfur dye of a second color to the dyebath, the synthetic or wool component is dyed one color and the cellulosic component is dyed a different color.

Polyester/cotton 50/50 spun yarns suitable for use as the warp yarns of denim fabric are obtained by first dyeing the yarns with indigo dye, coating the yarns with a dispersion of a polyol binder and a pigment that imparts coloration similar to indigo-dyed cotton fibers and then drying the yarns, and where appropriate, curing the coated yarn and supplying heat as by singeing to thermosol some of the pigment into the polyester fiber on the surface of the yarn. The polyol binder may be starch but preferably is polyvinyl alcohol in combination with a water soluble polyamide containing secondary amino groups in the polymer chain which have been reacted with epichlorohydrin. The pigment preferably is a combination of Color Index Disperse Blue 56 dye and carbon black.
摘要:
Process for the continuous dyeing of flat textile structures made of cellulose fibers and their mixtures with synthetic fiber materials by applying onto the web of fibrous material an aqueous solution of at least one reactive dyestuff and a fixation agent mixture of a liquid alkali metal silicate of the formula Me.sub.2.sup.I .multidot.x SiO.sub.2 (x=3-5) (water glass) and an aqueous alkali metal hydroxide solution, placing the material thus treated into a dwelling chamber, exposing the material in a cuttled-up or opened-out condition in said chamber to humid heat, so that the dyestuff is fixed by the dwelling operation, and finally removing the material again continuously from the dwelling chamber.

This invention relates to fabric treatments by which cotton and cellulosic blended fabrics can be provided with wrinkle resistance (smooth dry performance) and color at the same time. In particular, it provides a means by which cellulosic fabrics can be dyed with basic dyestuffs. In addition to a conventional means by which the entire fabric can be dyed with a basic dye, variations are achieved in which one side of the fabric is dyed one color and the other side of the fabric is dyed a second color. The color on the reverse side can be provided by means of either basic dyes or regular cotton dyes. The technique has also been extended for the printing of fabrics.
